IMPROVEMENT lN FIRE-PLACE GRATES.

Specification forming part of Letters Patent No. 1 64,150, dated June 8,1875; application filed May 15, 1875.

To all whom it mag concern:

Be it known that I, GEORGE W. CUMMINGS,

.of Franklin, in the county of Venango and State of Pennsylvania, haveinvented a new and valuable Improvement in Fire Place Grates; and I dohereby declare that the following is a full, clear, and exactdescription of the construction and operation of the same, referencebeing had to the annexed drawings, making a part of this specification,and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a front view of myfire-place, and Fig. 2 is a transverse vertical sectional view of thesame. Fig. 3 is a front view, and Figs. 4 and 5 are detail views.

The object of my invention is to improve the fire-place for whichLetters Patent of the United States were granted to me on the 22d day ofApril, 1872 and the nature of my invention consists in a novel manner offastening the false back to the back plate of the fireplace, leaving anair-space between them also, in an arched crown having ribs or flangesformed on it, and extending from side to side of the fire-place, for thepurpose of arresting the heat and throwing it into the room, incombination with an arched and beveled flange 011 the back part of thefront plate, arranged just over the outlet into the chimney, for thepurpose of preventing the escape of smoke into the room. The inventionfinally consists in novel means for constructing the several parts ofthe fire-place and putting the same together, as will be hereinafterexplained.

In the annexed drawings, A designates the front plate or facing of thefire-place; B B, the two jambs; G, the crown or top plate; D, the backplate, and E the false back, between which and the back plate is a spacefor the circulation of air, which air becomes heated and passes, throughperforations through plate E, into the fire-chamber, where it promotescombustion. The front plate A is rigidly secured to the front edges ofthe jambs by means of bolts, which are tapped through lugs I), formed onthe jambs, and shown in Fig. 3. On the back part of the plate A is anarch, provided with a flange, c, which is beveled, as shown in Fig. 2,and which extends over an'opening, 6', through which the heated .clinedthey will securely hold the false back in its place, but allow it toexpand and contract without cracking. The vertical edges of the backplate D have ribs cast on them, which form grooves to receive the rearvertical edges of the jambs, and serve, in combination with a horizontalrod, G, for securing the jambs and back plate together. The lower edgeof the back plate is received into notches made in offsets of the jambs.The lower side of the top plate 0 is provided with ribs h, which extendfrom side to side, and serve to arrest the heat and throw it into theroom.

J designates a basket-grate, at the corners of the vertical portion ofwhich hooks t are formed, which engage with j, and serve, in combinationwith lugs k, to hold the grate in its place. In combination with thegrate J I use a shaker, N, which is composed of longitudinal and crossbars, and hung so that it can be oscillated by means of a handle, P, forthe purpose of shaking out ashes and keeping the grate-bars free fromashes.

What I claim as new, and desire to secure byLettei-s Patent, is'

l. The combination of the perforated false back E, inclined studs f, andperforated back D, substantially as specified.

2. The arched crown 0, having ribs h, in combination with the frontplate A, provided with the beveled flange 0, extending rearwardly intothe flue, substantially as specified.

3. The back plate D, provided with ribs, in combination with the jambs Band rod G, substantially as and for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
